Author(s)
Geraldine S. Cheok, Kamel S. Saidi, Marek Franaszek, James J. Filliben, Nicholas Scott
A 3D imaging instrument is a non-contact measurement instrument used to rapidly obtain 3D information about a scene or object. The use of and the applications for these instruments have grown tremendously in the last decade. The expanded use of 3D imaging

Evaluation of Ultra-Wideband Technology for use in 3D Locating Systems

September 28, 2010
Author(s)
Adam P. Kopp, Kamel S. Saidi, Hiam Khoury
A high-powered (5 Watt peak power) ultra-wideband (UWB) ranging system was evaluated for use as the basis for a 3-Dimensional (3D) locating system by comparing tracking results to a ground truth system. The UWB ranging system is composed of five ranging

Proceedings of the GSA 3D Imaging Workshop, February 28, 2011 (NIST TN 1699)

December 9, 2009
Author(s)
Geraldine S. Cheok, Marek Franaszek, Kamel S. Saidi
The General Services Administration (GSA) has been involved in 3D imaging since the early 2000s. Since 3D imaging was a relatively new technology at that time, GSA needed to develop and provide initial guidance to their project managers (PMs) on 3D imaging

Fitting Spheres to Range Data from 3D Imaging Systems

October 1, 2009
Author(s)
Marek Franaszek, Geraldine S. Cheok, Kamel S. Saidi, Christoph J. Witzgall
Two error functions used for nonlinear Least Squares (LS) fitting of spheres to range data from 3D imaging systems are discussed: orthogonal error function and directional error function. Both of the functions allow unrestricted gradient-based minimization

Gauging the Repeatability of 3D Imaging Systems by Sphere Fitting

September 30, 2009
Author(s)
Marek Franaszek, Geraldine S. Cheok, Kamel S. Saidi
Multiple scans of the same object acquired with 3D imaging system (e.g., laser scanner) in the same experimental conditions could provide valuable information about the instrument s performance (e.g., stability, existence of bias, measurement error)

Target Penetration of Laser-Based 3D Imaging Systems

January 19, 2009
Author(s)
Geraldine S. Cheok, Kamel S. Saidi, Marek Franaszek
The ASTM E57.02 Test Methods Subcommittee is developing a test method to evaluate the ranging performance of a 3D imaging system. The test method will involve either measuring the distance between two targets or between an instrument and a target. The

June 4, 2008
Author(s)
Geraldine S. Cheok, Alan M. Lytle, Kamel S. Saidi
As the applications for 3D imaging systems continue to grow, the need for standards to evaluate these systems has become more critical. The ASTM E57 3D Imaging committee established in 2006 was formed specifically to develop standard terminology, test
